None of these premises hold with the current system. You can lament or 
debate that all you like but the facts remain. So in the current system 
it is not acceptable, in my opinion, to push a change that includes 
build instructions for platform X without a build of platform X having 
been tested. So if a submitter can't do that test themselves then they 
need to collaborate with someone who can.
